ROLLER FOR HAT-SIZING MACHINES.

Specification of Letters Patent.

Patented March 3, 1908.

Application led April 7. 1903. Serial No, 151,436.

To all whom it may concern:

Be it known that I, JOHN F. WILLIAMS, a citizen of the United States, residing at I/Vest Orange, in the county of Essex and State of New Jersey, have invented and produced a new and useful Improvement in Rollers for Hat-Sizing Machines 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of hatsizing machines in which a group of three or more rollers, either straight or centrally concaved, are employed to reduce or shrink the felt, and more particularly the invention relates to the rollers used in such machines.

The objects of the invention are to secure a roller which shall be durable; to obtain a roller upon which the steam and liquids will not act to secure a roller having a smooth surface, even when first used; to provide means for mounting said rollers so that the same can be exchanged or renewed with ease and convenience, and to obtain other advantages and results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the improved roller for hat-sizing machines, and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claims.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure l is a plan view' of a roller of my improved construction, and Fig. 2 is an end view of the same; Fig. 3 is a detail view of an end box or bushing detached from said roller; Fig. 4 is a view of the inner' end of said bushing, and Eig. 5 is a central longitudinal section of an end portion of a roller showing the bushing seated therein.

In said drawings, a indicates a roller of my improved construction, said roller being formed in one integral piece, preferably of clay or any suitable similar substancecommonly used in the art of making pottery, pressed or molded into suitable form and later glazed on its exterior surface for poses hereinafter referred to.

The roller comprises a body portion b, of circular cross-section and preferably smallest at its middle, or longitudinally concaved. Upon the exterior of said body portion b, are disposed circumferential series of short longitudinal ribs, d, d; any number ofsaid circumferential series may be employed, but for purposes of illustration I have shown five; likewise each series may contain any number of ribs. The inclined ribs of the end series project farthest from the longitudinal axis of the roll and give a concavous effect to the roll whereby the hat rolls are retained at the center. The ribs of the center have a somewhat less projection, while the intermediate series between the center and opposite end series have a still less projection and form annular recesses around the periphery of the roll which tend to give an uneven charpuracter to the periphery of the roll and thus facilitate the sizing operation. The ribs of each circumferential series are preferably staggered or alternately disposed. with respect to those of the next adjacent series, although they might be in alinement. Each rib' is of any suitable height, preferably about nine-sixteenths of' an inch, and slightly tapers outward having its corners rounded as at e, and its base broadened as at f, referring more particularly to Fig. 2 of the drawings. A roller is thus provided which is strong and which is free from joints. Moreover, it is not affected by swelling and shrinking and is not susceptible to wear, so that not only is the roller more durable and free from needing repairs, but furthermore, it always remains unchanged, and thus an improved productJ results from the use of such rollers. Again, the surface of the roller being glazed is always smooth, even when first used, so that it produces the best effect upon the hats. The ribs cannot become loose upon the body of the roller, and by reason of their shape and the natural strength of the material of which the roller is made, are not likely to be broken off. Heretofore the expense of repairing the rollers of a hat-sizing machine has been very considerable, and every three to six months it has been necessary to renew the rollers with an entirely new set, thereby entailing great expense. By my construction I provide a roller which will remain in service indefinitely, since it has no parts to work loose, Will not swell or shrink, and. is not in danger of being broken by the soft bundle of hats operated upon.

F or purposes of mounting zmy improved i roller I prefer to form the same hollow or with a central passage g, which provides sockets at the ends, and these sockets have longitudinal grooves h, in their Walls. One end of a metal box or bushing i, is then adapted to be set in each socket, having at its inner end short lateral Wings or lugs j, to lie in the groove h. Cement k, is then poured into the socket, around the bushing,y whereby the same is firmly held in position. Said box or bushing is longitudinally bored out to receive a shaft end Z, for supporting the roller, a set screw fm, in one side of the box or bushing i, serving to clamp the parts together. Preferably a peripheral flange n, upon the bushing, lies against the end of the roller a, as shown.

Obviously means for mounting my improved roller other than those speciiically described might be employed, and various changes can be made in the exact composition of the roller itself Without a'ecting its .characteristics set forthas the essential features of this invention, and I therefore do not Wish to be understood as limiting myself by the positive terms herein employed, except as the state of the art may require.

I have discovered that the glazed clay or pottery materials are not affected by the chemicals employed in the hat sizing fluids and hence the said fluids Will not deteriorate by contact With such rollers as they would by the use of metal, for example. The glazing presents a smooth surface freefrom splinters ard similar roughnesses tending to injure the fe t.

Having thus described the invention, What I claim as new is l. In a hat-sizing roller, the combination with a body portion comprising a single piece of pottery, and having sockets at its ends with longitudinal grooves in their Walls, of bushings inserted in said sockets and having radial lugs to enter said grooves, and a shaft in each of said bushings.

2. AIn a hat-sizing roller, the combination with a body portion formed of a single piece of pottery and having sockets in its ends with longitudinal grooves in their Walls, of bushings adapted to enter said sockets and having exterior lugs adapted to lie in the saidy grooves, said lugs being shorter than said grooves and providing space for cement, and a shaft in each of said bushings.

3. The improved hat sizing machine roller, comprising the roller body and ribs arranged longitudinally and in series, the alternate series of ribs projecting farther from the axis of the roll and forming annular recesses, and the end ribs being inclined to the axis of the roll and giving a concaved general outline to the periphery of the roll, the said body and ribs being in one integral piece of pottery vvare.

In testimony that I claim the foregoing, I

have hereunto set my hand this 19th day of March, 1903.

JOHN F. WILLIAMS.
